ABSTRACT

Aspects of filtering coefficient configuration operations are described. Some aspects include a user equipment (UE) decoding a measurement configuration information element (IE) including a measurement quantity parameter, a reference signal (RS)-type filter configuration and at least one filter coefficient. In some aspects, the UE filters at least one of a cell measurement result and a beam measurement result, according to the measurement configuration IE. If the measurement quantity parameter indicates the cell measurement quantity, the UE can filter the cell measurement result according to the RS type filter configuration and the filter coefficient to determine a measurement evaluation input for a measurement reporting operation. If the measurement quantity parameter indicates the beam measurement quantity, the UE can filter the beam measurement result according to the RS type filter configuration and the filter coefficient to determine a beam measurement selection input for a beam measurement selection operation.

PRIORITY CLAIM

This application is a continuation of U.S. patent application Ser. No. 16/162,541, filed Oct. 17, 2018, which claims priority to U.S. Provisional Patent Application Ser. No. 62/575,281 filed Oct. 20, 2017, each of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

Aspects pertain to wireless communications. Some aspects relate to wireless networks including 3GPP (Third Generation Partnership Project) networks, 3GPP LTE (Long Term Evolution) networks, 3GPP LTE-A (LTE Advanced) networks, wireless local area networks (WLANs), fifth-generation (5G) networks including 5G new radio (NR) networks, next-generation (NG) networks, 5G-LTE networks, and software-defined networks (SDNs).

BACKGROUND

In New Radio (NR) systems, signal measurement filtering can be used for radio resource management (RRM). One difference between NR and Long Term Evolution (LTE) systems is that NR includes beam level measurements and cell quality evaluation from beams. As a result, additional filters signal measurement filtering can be used for beam reporting purposes. Filtering coefficient configurations and signalling methods are needed for cell level measurements and beam level measurements.

DETAILED DESCRIPTION

The following description and the drawings sufficiently illustrate aspects to enable those skilled in the art to practice them. Other aspects may incorporate structural, logical, electrical, process, and other changes. Portions and features of some aspects may be included in, or substituted for, those of other aspects. Aspects set forth in the claims encompass all available equivalents of those claims.

Radio resource management (RRM) configuration can include measurements that are performed by user equipment (UE). Such measurements can include intra-frequency NR measurements, inter-frequency NR measurements or inter-radio access technology (RAT) measurements for Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access (E-UTRA). Measurements can be beam level measurements or cell level measurements. In some aspects, a network entity can configure a measurement type to be performed, such as an access point (AP), radio access network (RAN) node or base station (BS) described in further detail with respect to FIGS. 2A and 2B. Configuring the measurement type can include encoding, and transmitting within signalling to a UE (e.g., UE 201 or 203 of FIG. 2A or 2B), a measurement configuration. In a non-limiting example, a measurement configuration can define a frequency of measurement, a signal type for measurement and a location within time-frequency resources that a UE is to measure.

A measurement configuration can define one or several reporting configurations, and a reporting configuration can define reporting criteria, for example, criteria by which a UE decides whether to generate a measurement report and criteria by which the network decides whether to handover the UE from one cell to another cell (e.g., reporting events). In some aspects, reporting criteria can include event triggered reporting, periodic reporting and event triggered periodic reporting. In some aspects, the measurement configuration can include filter coefficients and the UE may use the filter coefficients to filter measurements for evaluating reporting criteria and for determining measurements to report. Certain filtering coefficients are specific to the RRC protocol layer, and the UE can receive such filter coefficients within RRC signalling from a network entity (e.g., AP, BS, RAN node) and apply the coefficients in filtering operations on measurements. Aspects herein describe, in part, measurement configurations and specifically configurations of filter coefficients.

FIG. 1 illustrates a diagram of measurement and filtering system, in accordance with some aspects. Operations represented in the measurement and filtering system 100, or portions of the operations represented, may be performed by any one or more of the network entities or devices described herein. For example, the network entities or devices, including network function virtualization (NFV)-based or software-defined networking (SDN)-based network entities or devices of FIGS. 2A-2J.

In some aspects, the measurement and filtering system 100 can include filtering operations that can involve multiple protocol layers (e.g., layers of a protocol functions of the protocol layers) in a network system. Filtering operations, for example, can be performed in a layer 1 protocol layer (e.g., physical layer) or in a layer 3 protocol layer (e.g., radio resource control (RRC) layer), or both layer 1 and layer 3 of the network system. Details of such protocol layers are further described with respect to FIGS. 4, 7 and 8. The measurement and filtering system 100 can include operations such as beam measurement 115, physical layer filtering 104 (e.g., layer 1 filtering), beam consolidation and/or selection 105, RRC layer filtering for cell quality 107, evaluation of reporting criteria 109, RRC layer filtering of beam measurements 111 and beam selection for measurement reporting 113.

A device (e.g., UE 201 or 203) can measure one or multiple received beams, such as beams transmitted from an AP (e.g., RAN node 213, 215, 243) in the network (e.g., system 200A, 200B), for example, processing circuitry within an apparatus of the UE can configure transceiver circuitry to receive such beams. According to the UE implementation 103 can filter the beam measurements. In certain aspects, a filter (e.g., layer 1 filter or layer 3 filter) can be configured to perform filtering of beam measurements and/or cell measurements. The filter can be included, for example, within an apparatus and/or circuitry of the UE, and in some instances can be a virtualized or software defined filter function.

In some aspects, the device can filter the beam measurements according to a UE-specific implementation in layer 1 (e.g., physical layer). As a result of filtering the beam measurements, the UE can generate beam specific measurements 117 that can be reported by the physical layer to the RRC layer after the physical layer filtering. Using the beam specific measurements 117 as inputs, the UE can consolidate beam specific measurements 105 to derive a cell quality value 119. In some aspects, beam consolidation and/or beam selection can be configured and controlled by the AP through RRC signalling transmitted from the AP to the UE.

In some aspects, the RRC signalling can also include a configuration of RRC layer (e.g., layer 3) filtering parameters and/or filtering coefficients. The UE can use the filtering parameters and coefficients to filter the measurements, for example, using RRC layer filtering. In some aspects, using the cell quality value 119 as an input, the UE can use RRC layer filtering for cell quality 107. As a result of filtering for cell quality 107, the UE can generate input values 121 for evaluation of reporting criteria. In certain aspects, one or more additional inputs 123 may be used for the evaluation of reporting criteria.

The evaluation of reporting criteria 109 can include evaluating whether measurement reporting is to be used to report measurements to a network entity (e.g., AP, RAN node). A reporting event can be an event where a signal strength of a neighbor cell becomes an offset better than a signal strength of a primary cell (PCell) (e.g., A3 event) or where the signal strength of the neighbor cell becomes an offset better than the signal strength of a secondary cell (SCell) (e.g., A6 event). In some aspects, reported measurements can include information to be used for RRM, reference signal received power (RSRP), reference signal received quality (RSRQ), and/or signal-to-interference-plus-noise ratio (SINR). The evaluation can be based on more than one flow of measurements or inputs 121, for example, for the purpose of comparing between different measurements (e.g., 121 and 123). In some aspects, the UE can evaluate the reporting criteria every time a new measurement result is reported at inputs 121 and 123. Reporting criteria can be configured through RRC signalling (e.g., transmitted by an AP, BS or RAN node to a UE).

In some aspects, the UE or a filter within the UE can perform RRC layer (e.g., layer 3) beam filtering 111 on measurements, such as the beam-specific measurements 117. Beam filtering can be configured by RRC signalling that can include filtering parameters and/or filtering coefficients, of which the UE can use for filtering beam-specific measurements 117. As a result of the beam filtering 111, the UE can generate a filtered beam-specific measurement 127 that can be used as an input for selecting a number of measurements 113 to be evaluated and potentially reported in a measurement report. In certain aspects, the beam-specific measurements 117 and the filtered beam-specific measurement 127 can be a number of beams (e.g., K beams) that can correspond to measurements in certain time-frequency resources. For example, time-frequency resources, such as synchronization signal blocks (SSB) (e.g., NR-SS block) or channel state information-reference signals (CSI-RS). Such resources can be configured by a network entity (e.g., BS, RAN node) through the RRC layer and detected by the UE through the physical layer.

The UE can perform beam selection for beam reporting, in some aspects, and the UE can select a number of measurements from the filtered beam-specific measurements 127. The selected filtered beam-specific measurements 127 can be used for measurement reporting 129 (e.g., X beams) and the selecting can be configured through RRC signalling. A measurement report, including cell measurement quantities and beam measurement quantities that are filtered according to filter coefficients, can be encoded by processing circuitry of the UE and transmitted by transceiver circuitry to the AP, BS or RAN node. In some aspects, the measurement configuration in RRC signalling can include one or more parameters, information elements (IE) and/or coefficients, such as a measurement object, a reporting configuration, a measurement identity, and a quantity configuration.

The measurement object parameter can include information such as a list of objects on which the UE shall perform measurements. For example, a measurement object can include a list of measurement objects to add, remove and/or to modify. In certain aspects, the UE can store in memory the list of measurement objects and add, remove or modify the list according to the measurement object parameters or coefficients in the RRC signalling. In some aspects, the RRC signalling can include different parameters or coefficients to indicate different measurement objects (e.g., two measurement objects are indicated by separate coefficients), and in other aspects, the same coefficient can indicate more than one measurement object.

In some aspects, the reporting configuration parameter can include a list of reporting configurations and a single measurement object can correspond to one or multiple reporting configurations. A reporting configuration can consist of a reporting criterion that triggers the UE to send a measurement report that can be a periodical or a single event description. The reporting configuration can also include a reference signal (RS) type indication that the UE can use for beam and cell measurement results (e.g., SSB or CSI-RS measurement results). The reporting configuration can also include a reporting format including the quantities per cell and per beam, and other associated information such as the maximum number of cells and the maximum number beams per cell, that the UE can include in a measurement report.

In some aspects, a measurement identity parameter can include a list of measurement identities where a measurement identity can link one measurement object with one reporting configuration. By configuring multiple measurement identities, more than one measurement object can be linked to the same reporting configuration, and more than one reporting configuration can be linked to the same measurement object. In certain aspects, the measurement identity is also included in the measurement report that triggers the reporting, serving as a reference to the network. In some aspects, a quantity configuration parameter can define a measurement filtering configuration that can be used for all event evaluation and related reporting, and for periodical reporting of the measurement. In some aspects, the quantity configuration parameter (e.g., IE) can specify measurement quantities and RRC layer (e.g., layer 3) filtering coefficients, for example, for NR measurements and E-UTRA measurements.

The quantity configuration IE, for example, can include one or more parameters and/or coefficients (e.g., layer 3 filtering coefficients) for the UE to use in filtering cell and beam measurements. Such parameters (e.g., coefficients) can include, for example, separate coefficients for cell quantity and beam quantity, separate coefficients for reference signal types such as a synchronization signal block (SSB)-based coefficient or a channel state information-reference signal (CSI-RS)-based coefficient, and separate filter coefficients (e.g., layer 3 filtering coefficients) such as a reference signal received power (RSRP) filter coefficient, a reference signal received quality (RSRQ) filter coefficient and a reference signal-signal to interference plus noise ratio (RS-SINR) filter coefficient. In some aspects, the UE can use the measurement configuration (e.g., received in RRC signalling), and any of the parameters or coefficients included therein, to perform beam and cell measurements and measurement reporting, as described further below with respect to FIG. 11.

FIG. 2A illustrates an architecture of a system 200A of a network in accordance with some aspects. In some aspects, the system 200A may be configured for the measurement and filtering operations and/or filtering coefficient signalling methods described herein. The system 200A is shown to include a user equipment (UE) 201 and a UE 201/203. The UEs 201/203 may be smartphones (e.g., handheld touchscreen mobile computing devices connectable to one or more cellular networks) or any mobile or non-mobile computing device, such as Personal Data Assistants (PDAs), pagers, laptop computers, desktop computers, wireless handsets, or any computing device including a wireless communications interface. In some aspects, the UE 201/203 may be Internet-of-Things (IoT)-enabled devices, configured to communicate with a RAN 210 or a core network (CN) 221, including but not limited to vehicles or drones.

In some aspects, any of the UEs 201/203 can comprise an Internet of Things (IoT) UE, which can comprise a network access layer designed for low-power IoT applications utilizing short-lived UE connections. An IoT UE can utilize technologies such as machine-to-machine (M2M) or machine-type communications (MTC) for exchanging data with an MTC server or device via a public land mobile network (PLMN), Proximity-Based Service (ProSe) or device-to-device (D2D) communication, sensor networks, or IoT networks. The M2M or MTC exchange of data may be a machine-initiated exchange of data. An IoT network describes interconnecting IoT UEs, which may include uniquely identifiable embedded computing devices (within the Internet infrastructure), with short-lived connections. The IoT UEs may execute background applications (e.g., keep-alive messages, status updates, etc.) to facilitate the connections of the IoT network.

The UEs 201/203 may be configured to connect, in a wired or wireless configuration, e.g., communicatively couple, with a radio access network (RAN) 210. The RAN 210 may be, for example, an Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN), a NextGen RAN (NG-RAN), 5G RAN, or some other type of RAN. The UEs 201/203 utilize connections 205, each of which comprises a physical communications interface or layer (discussed in further detail below); in this example, the connections 205 are illustrated as an air interface to enable communicative coupling, and can be consistent with cellular communications protocols, such as a Global System for Mobile Communications (GSM) protocol, a code-division multiple access (CDMA) network protocol, a Push-to-Talk (PTT) protocol, a PTT over Cellular (POC) protocol, a Universal Mobile Telecommunications System (UMTS) protocol, a 3GPP Long Term Evolution (LTE) protocol, a fifth generation (5G) protocol, a New Radio (NR) protocol, and the like.

In this aspect, the UEs 201/203 may further directly exchange communication data via a ProSe interface 207. The ProSe interface 207 may alternatively be referred to as a sidelink interface comprising one or more logical channels, including but not limited to a Physical Sidelink Control Channel (PSCCH), a Physical Sidelink Shared Channel (PSSCH), a Physical Sidelink Discovery Channel (PSDCH), and a Physical Sidelink Broadcast Channel (PSBCH). The UE 201/203 is shown to be configured to access an access point (AP) 211 via connection 209. The connection 209 can comprise a local wireless connection, such as a connection consistent with any IEEE 802.11 protocol, where the AP 211 would comprise a wireless fidelity (WiFi®) router. In this example, the AP 211 is shown to be connected to the Internet without connecting to the core network of the wireless system (described in further detail below).

The RAN 210 can include one or more access nodes (ANs) or access points (APs) that enable the connections 205, for example, for filter coefficient configuration and measurement operations. These ANs can be referred to as base stations (BSs), NodeBs, evolved NodeBs (eNBs), next Generation NodeBs (e.g., gNB, ng-eNB), RAN nodes, and so forth, and can comprise ground stations (e.g., terrestrial access points) or satellite stations providing coverage within a geographic area (e.g., a cell). In some aspects, the communication nodes 213 and 215 can be transmission/reception points (TRPs). In instances when the communication nodes 213 and 215 are NodeBs (e.g., eNBs or gNBs), one or more TRPs can function within the communication cell of the NodeBs. In some aspects, a NodeB can be a E-UTRA-NR (EN)-gNB (en-gNB) configured to support E-UTRA-NR Dual Connectivity (EN-DC) (e.g., multi-RAT Dual Connectivity (MR-DC)), in which a UE may be connected to one eNB that acts as a master node (MN) and one en-gNB that acts as a secondary node (SN).

The RAN 210 may include one or more RAN nodes for providing macrocells, e.g., macro RAN node 213, and one or more RAN nodes for providing femtocells or picocells (e.g., cells having smaller coverage areas, smaller user capacity, or higher bandwidth compared to macrocells), e.g., low power (LP) RAN node 215. Any of the RAN nodes 213 and 215 can terminate the air interface protocol and can be the first point of contact for the UEs 201/203. In some aspects, any of the RAN nodes 213 and 215 can fulfill various logical functions for the RAN 210 including, but not limited to, radio network controller (RNC) functions such as radio bearer management, uplink and downlink dynamic radio resource management and data packet scheduling, and mobility management. In an example, any of the nodes 213 or 215 can be a new generation node-B (gNB), an evolved node-B (eNB), or another type of RAN node.

In accordance with some aspects, the UEs 201/203 can be configured to communicate using Orthogonal Frequency-Division Multiplexing (OFDM) communication signals with each other or with any of the RAN nodes 213 and 215 over a multicarrier communication channel in accordance various communication techniques, such as, but not limited to, an Orthogonal Frequency-Division Multiple Access (OFDMA) communication technique (e.g., for downlink communications) or a Single Carrier Frequency Division Multiple Access (SC-FDMA) communication technique (e.g., for uplink and ProSe or sidelink communications), although the scope of the aspects is not limited in this respect. The OFDM signals can comprise a plurality of orthogonal subcarriers.

In some aspects, a downlink resource grid can be used for downlink transmissions from any of the RAN nodes 213 and 215 to the UEs 201/203, while uplink transmissions can utilize similar techniques. The grid can be a time-frequency grid, called a resource grid or time-frequency resource grid, which is the physical resource in the downlink in each slot. Such a time-frequency plane representation is a common practice for OFDM systems, which makes it intuitive for radio resource allocation. Each column and each row of the resource grid corresponds to one OFDM symbol and one OFDM subcarrier, respectively. The duration of the resource grid in the time domain corresponds to one slot in a radio frame. The smallest time-frequency unit in a resource grid is denoted as a resource element. Each resource grid may comprise a number of resource blocks, which describe the mapping of certain physical channels to resource elements. Each resource block comprises a collection of resource elements; in the frequency domain, this may represent the smallest quantity of resources that currently can be allocated. There are several different physical downlink channels that are conveyed using such resource blocks.

The physical downlink shared channel (PDSCH) may carry user data and higher-layer signalling to the UEs 201/203. The physical downlink control channel (PDCCH) may carry information about the transport format and resource allocations related to the PDSCH channel, among other things. It may also inform the UEs 201/203 about the transport format, resource allocation, and H-ARQ (Hybrid Automatic Repeat Request) information related to the uplink shared channel. Typically, downlink scheduling (assigning control and shared channel resource blocks to the UE 102 within a cell) may be performed at any of the RAN nodes 213 and 215 based on channel quality information fed back from any of the UEs 201/203. The downlink resource assignment information may be sent on the PDCCH used for (e.g., assigned to) each of the UEs 201/203.

The PDCCH may use control channel elements (CCEs) to convey the control information. Before being mapped to resource elements, the PDCCH complex-valued symbols may first be organized into quadruplets, which may then be permuted using a sub-block interleaver for rate matching. Each PDCCH may be transmitted using one or more of these CCEs, where each CCE may correspond to nine sets of four physical resource elements known as resource element groups (REGs). Four Quadrature Phase Shift Keying (QPSK) symbols may be mapped to each REG. The PDCCH can be transmitted using one or more CCEs, depending on the size of the downlink control information (DCI) and the channel condition. There can be four or more different PDCCH formats defined in LTE with different numbers of CCEs (e.g., aggregation level, L=1, 2, 4, or 8).

Some aspects may use concepts for resource allocation for control channel information that are an extension of the above-described concepts. For example, some aspects may utilize an enhanced physical downlink control channel (EPDCCH) that uses PDSCH resources for control information transmission. The EPDCCH may be transmitted using one or more enhanced control channel elements (ECCEs). Similar to above, each ECCE may correspond to nine sets of four physical resource elements known as an enhanced resource element groups (EREGs). An ECCE may have other numbers of EREGs in some situations.

Entities within a RAN (e.g., RAN 210), such as RAN Nodes (e.g., 213, 215), can be connected (e.g., communicatively coupled), in a wired or wireless configuration, to one or more network entities, including to one another. For example, a connection can include a backhaul connection. Wired connections can include ethernet, coaxial cable, fiber optic cable, although aspects are not so limited. The RAN 210 is shown to be communicatively coupled to a core network (CN) 221 via an S1 interface 217. In aspects, the CN 221 may be an evolved packet core (EPC) network, a NextGen Packet Core (NPC) network, or some other type of CN (e.g., as illustrated in reference to FIGS. 2B-2I). In this aspect the S1 interface 217 is split into two parts: the S1-U interface 214, which carries traffic data between the RAN nodes 213 and 215 and the serving gateway (S-GW) 231, and the S1-mobility management entity (MME) interface 219, which is a signalling interface between the RAN nodes 213 and 215 and MMEs 223.

In this aspect, the CN 221 comprises the MMEs 223, the S-GW 231, the Packet Data Network (PDN) Gateway (P-GW) 223, and a home subscriber server (HSS) 225. The MMEs 223 may be similar in function to the control plane of legacy Serving General Packet Radio Service (GPRS) Support Nodes (SGSN). The MMEs 223 may manage mobility aspects in access such as gateway selection and tracking area list management. The HSS 225 may comprise a database for network users, including subscription-related information to support the network entities' handling of communication sessions. The CN 221 may comprise one or several HSSs 225, depending on the number of mobile subscribers, on the capacity of the equipment, on the organization of the network, etc. For example, the HSS 225 can provide support for routing/roaming, authentication, authorization, naming/addressing resolution, location dependencies, etc.

The S-GW 231 may terminate the S1 interface 219 towards the RAN 210, and route data packets between the RAN 210 and the CN 221. In addition, the S-GW 231 may be a local mobility anchor point for inter-RAN node handovers and also may provide an anchor for inter-3GPP mobility. Other responsibilities may include lawful intercept, charging, and some policy enforcement. The P-GW 233 may terminate an SGi interface toward a PDN. The P-GW 233 may route data packets between the CN 221 and external networks such as a network including the application server 237 (alternatively referred to as application function (AF)) via an Internet Protocol (IP) interface 227. The P-GW 233 can also communicate data to other external networks 235, which can include the Internet, IP multimedia subsystem (IPS) network, and other networks. Generally, the application server 237 may be an element offering applications that use IP bearer resources with the core network (e.g., UMTS Packet Services (PS) domain, LTE PS data services, etc.). In this aspect, the P-GW 233 is shown to be communicatively coupled to an application server 237 via an IP communications interface 227. The application server 237 can also be configured to support one or more communication services (e.g., Voice-over-Internet Protocol (VoIP) sessions, PTT sessions, group communication sessions, social networking services, etc.) for the UEs 201/203 via the CN 221.

The P-GW 233 may further be a node for policy enforcement and charging data collection. Policy and Charging Enforcement Function (PCRF) 229 is the policy and charging control element of the CN 221. In a non-roaming scenario, there may be a single PCRF in the Home Public Land Mobile Network (HPLMN) associated with a UE's Internet Protocol Connectivity Access Network (IP-CAN) session. In a roaming scenario with local breakout of traffic, there may be two PCRFs associated with a UE's IP-CAN session: a Home PCRF (H-PCRF) within a HPLMN and a Visited PCRF (V-PCRF) within a Visited Public Land Mobile Network (VPLMN). The PCRF 229 may be communicatively coupled to the application server 237 via the P-GW 233. The application server 237 may signal the PCRF 229 to indicate a new service flow and select the appropriate Quality of Service (QoS) and charging parameters. The PCRF 229 may provision this rule into a Policy and Charging Enforcement Function (PCEF) (not shown) with the appropriate traffic flow template (TFT) and QoS class of identifier (QCI), which commences the QoS and charging as specified by the application server 237.

In an example, any of the nodes 213 or 215 can be configured to communicate to the UEs 201/203 (e.g., dynamically) by an antenna panel selection and a receive (Rx) beam selection that can be used by the UE for data reception on a physical downlink shared channel (PDSCH) as well as for channel state information reference signal (CSI-RS) measurements and channel state information (CSI) calculation. In an example, any of the nodes 213 or 215 can be configured to communicate to the UEs 201/203 (e.g., dynamically) by an antenna panel selection and a transmit (Tx) beam selection that can be used by the UE for data transmission on a physical uplink shared channel (PUSCH) as well as for sounding reference signal (SRS) transmission.

In some aspects, the communication network 240A can be an IoT network. One of the current enablers of IoT is the narrowband-IoT (NB-IoT). NB-IoT has objectives such as coverage extension, UE complexity reduction, long battery lifetime, and backward compatibility with the LTE network. In addition, NB-IoT aims to offer deployment flexibility allowing an operator to introduce NB-IoT using a small portion of its existing available spectrum, and operate in one of the following three modalities: (a) standalone deployment (the network operates in re-farmed GSM spectrum); (b) in-band deployment (the network operates within the LTE channel); and (c) guard-band deployment (the network operates in the guard band of legacy LTE channels). In some aspects, such as with further enhanced NB-IoT (FeNB-IoT), support for NB-IoT in small cells can be provided (e.g., in microcell, picocell or femtocell deployments). One of the challenges NB-IoT systems face for small cell support is the UL/DL link imbalance, where for small cells the base stations have lower power available compared to macro-cells, and, consequently, the DL coverage can be affected or reduced. In addition, some NB-IoT UEs can be configured to transmit at maximum power if repetitions are used for UL transmission. This may result in large inter-cell interference in dense small cell deployments.

FIG. 2B illustrates an exemplary Next Generation (NG) system architecture 200B in accordance with some aspects. Referring to FIG. 2B, the NG system architecture 200B includes NG-RAN 239 and a 5G network core (5GC) 241.

The UDM 291 can be configured to store subscriber profiles and data (similar to an HSS in a 4G communication system).

In some aspects, the 5G system architecture 200E includes an IP multimedia subsystem (IMS) 293 as well as a plurality of IP multimedia core network subsystem entities, such as call session control functions (CSCFs). More specifically, the IMS 293 includes a CSCF, which can act as a proxy CSCF (P-CSCF) 295 a serving CSCF (S-CSCF) 297, an emergency CSCF (E-CSCF) (not illustrated in FIG. 2E), or interrogating CSCF (I-CSCF) 299.

In some aspects, the 5G system architecture 200E can be configured to use 5G access control mechanism techniques described herein, based on access categories that can be categorized by a minimum default set of access categories, which are common across all networks. This functionality can allow the public land mobile network PLMN, such as a visited PLMN (VPLMN) to protect the network against different types of registration attempts, enable acceptable service for the roaming subscriber and enable the VPLMN to control access attempts aiming at receiving certain basic services. It also provides more options and flexibility to individual operators by providing a set of access categories, which can be configured and used in operator specific ways.

The SDN controller 308 is a centralized logic entity that can coordinate communications and requested information from the SDN application plane 302 to the SDN data plane 306. The SDN controller 308 can provide an abstracted view of the network to an SDN application 303, and this abstracted view may include information describing certain network events as well as statistics. The SDN controller 308 may comprise an NBI agent 324, SDN control logic 326, and a control-data-plane interface (CDPI) driver 328. The SDN controller 308 may communicate with the one or more network elements 316A-316B via the SDN CDPI 328. The SDN CDPI 328 can enable capabilities advertisement, statistics reporting, event notification, and programmatic control of forwarding operations.

A network element, for example, can be device within the network, such as a router, switch, RAN node, or a gateway. A network element 316 may comprise an SDN data path 318, a logical device of a network that includes forwarding and data processing capabilities. The SDN data path 318 can include an SDN CDPI agent 320, a forwarding engine 321, and a processing function 322, which can enable internal traffic processing or terminations for the network element 316 (e.g., SDN data path 318), and forwarding between external interfaces of the SDN data path 318. In certain aspects, the forwarding engine 321 and processing function 322 may be included in the SDN data path 318 as a set. The SDN data path 318 may comprise combined physical resources, such as circuitry, and one or more SDN data paths may be included within a single network element or defined across multiple network elements.

FIG. 3B is a block diagram of an SDN architecture 300B, in accordance with some aspects. The SDN architecture 300B can be implemented within any of the systems shown in FIG. 1 or 2A-2J, and can be configured for SDN-based or NFV-based data measurement and filtering and/or filtering coefficient configuration operations. In some aspects, the UE 330 (e.g., UE 201/203) may communicate with a network (e.g., system 200A, system 200B, system 200C) to access various IP services. In some aspects, the architecture of the network can be SDN-based and configured to include a control plane separated from user plane entities or functions (e.g., network elements). A tunnel-less transmission can be used for provisioning IP services for various devices to reduce messaging overhead. The UE 330 can access the network via a RAN node 332. The RAN node 332 can communicate with a network controller 334 to request IP services provisioning for the UE 330. In certain aspects, the network controller 334 may be an SDN-based network controller. The network controller 334 can communicate with a repository 336 (e.g., subscription repository) to authenticate the UE 330, and the subscription repository 336 can be configured to store (e.g., in memory) device and service subscription information (e.g., device and service subscription information for the UE 330).

In various aspects, the RAN node 332, the network controller 334, or a combination of the RAN node 332 and the network controller 334, can provision a requested IP service (e.g., requested by the UE 330). IP service provisioning can include allocating a group of IP addresses. For example, a pool of IPv4 addresses or an IPv6 prefix may be allocated for a requested IP service. In some aspects, a mobile network operator (MNO) can preconfigure the group of IP addresses. The preconfigured group of IP addresses may be stored, for example, within memory of one or more of the subscription repository 336, the network controller 334, or the RAN node 332. If the RAN node 332 allocates the group of IP addresses, the RAN node 332 may request the group of IP addresses from the network controller 334.

The network controller 334 can request the group of IP addresses from the subscription repository 336. A device, such as the RAN node 332, network controller 334, or a router can identify a requested IP service by a group of IP addresses (e.g., the allocated group of IP addresses) and can use an IP address of a packet to identify a received packet and determine a routing policy for forwarding the packet to an appropriate data gateway (e.g., data gateway 338A, data gateway 338B, data gateway 338C), router, or an endpoint (e.g., 104B).

The network controller 334 can also configure devices, such as one or more data gateways (e.g., 338A, 338B, and 108) or routers (e.g., 106), for operations related to the requested IP service in a particular packet data network (PDN). For example, the network controller 334 can configure such devices with routing tables (e.g., flow tables, forwarding tables) for implementing a routing policy. In some aspects, the routing policies may be based on information regarding the PDN. As part of the data gateway configuration, the network controller 334 may provide routing policies to the RAN node 332, the data gateways, or the routers (e.g., 106). In some aspects, if the RAN node 332 receives the routing policies, the RAN node 332 may provide the routing policies to the data gateways.

In some aspects, the SDN architecture 300A can provide one or more network elements as virtualized services, for example, a controller (e.g., SDN controller), router, switch, RAN node, gateway, or various other network elements. These can be virtualized services of system 100 or systems 200A and 200B.

In some aspects, virtualized network elements can be implemented in different planes of the SDN architecture 300A. For example, the SDN architecture 300A can include a router (e.g., virtualized router), switch (e.g., virtualized switch), or other virtualized network elements that are implemented in the data plane 306 of the SDN architecture 300A. The SDN architecture 300A can also include a controller (e.g., SDN controller), or other virtualized network elements that are implemented in the control plane 304 of the SDN architecture 300A.

In some aspects, the SDN architecture 300A, including the virtualized network elements or services, can also provide virtualized network functions. Network function virtualization (NFV) can facilitate programmability and flexibility of network functions, such as functions performed by virtualized network elements (e.g., routers, switches, controllers, etc.). In some aspects, such virtualized functions can include measurement and filtering and/or filtering coefficient configuration operations, as described herein.

In an SDN (e.g., SDN architecture 300A), virtualized network elements in the control plane 304, such as the SDN controller, can maintain and configure a global state of the network. The virtualized network elements (e.g., virtualized network functions) in the data plane 306, such as a virtualized router or switch (e.g., virtualized router functionality or virtualized switching functionality), can operate as a data path configured for receiving data packets, identifying destination addresses for the data packets, and forwarding the data packets according to the identified destination addresses. In some aspects, such virtualized network elements can identify the destination addresses by referring to forwarding or routing tables that can include information that is structured according to routing policies and rules. Routing policies and rules may be established by network entities within the control plane, for example, the SDN controller. An example of a virtualized function that can be performed within the SDN architecture 300A or NFV system 1300 includes measurement and filtering and/or filtering coefficient configuration operations.

FIG. 3C is a block diagram illustrating components, according to some example aspects, of a system 300C to support NFV. The NFV system 300C, can include virtualized functions of the network entities of one or more of systems 100 or the systems shown in FIGS. 2A-2J. In some aspects, the NFV system 300C can include virtualized functions of the SDN network architecture of system 300A or 300B. Virtualized functions can include measurement and filtering operations and/or filtering coefficient signalling methods described herein.

The system 300C is illustrated as including a virtualized infrastructure manager (VIM) 340, a network function virtualization infrastructure (NFVI) 342, a VNF manager (VNFM) 344, virtualized network functions (VNFs) 346, an element manager (EM) 348, an NFV Orchestrator (NFVO) 350, and a network manager (NM) 352.

The VIM 340 manages the resources of the NFVI 342. The NFVI 342 can include physical or virtual resources and applications (e.g., including hypervisors) used to execute the system 300C. The VIM 340 can manage the life cycle of virtual resources with the NFVI 342 (e.g., creation, maintenance, and tear down of virtual machines (VMs) associated with one or more physical resources), track VM instances, track performance, fault and security of VM instances and associated physical resources, and expose VM instances and associated physical resources to other management systems. The VNFM 344 can manage the VNFs 346, and can configure and control network resources (e.g., in the SDN domain). The VNFs 346 can be used to execute EPC or 5GC components/functions and RAN components/functions. The VNFM 344 can manage the life cycle of the VNFs 346 and track performance, fault and security of the virtual aspects of VNFs 346. The EM 348 can track the performance, fault and security of the functional aspects of VNFs 346. The tracking data from the VNFM 344 and the EM 348 may comprise, for example, performance measurement (PM) data used by the VIM 340 or the NFVI 342. Both the VNFM 344 and the EM 348 can scale up/down the quantity of VNFs of the system 300C.

The NFVO 350 can coordinate, authorize, release and engage resources of the NFVI 342 in order to provide the requested service (e.g., to execute an EPC function, component, or slice). The NM 352 may provide a package of end-user functions with the responsibility for the management of a network, which may include network elements with VNFs, non-virtualized network functions, or both (management of the VNFs may occur via the EM 348). In some aspects, the VNFM 344 can manage virtualized functions of a network router or switch (e.g., router or switch 106A), and a network controller (e.g., SDN controller 308, network controller 334). In certain aspects, the virtualized router or switch functions can exist in the data plane of the SDN domain (e.g., data plane 306 in SDN architecture 300A) and the controller functions can exist in the control plane of the SDN domain (control plane 304 in SDN architecture 300A). In some aspects, the VNFM 344 can manage virtualized measurement and filtering operations and/or filtering coefficient signalling methods.

FIG. 4 illustrates protocol functions that may be implemented within or by devices of a network architecture, in accordance with some aspects. For example, such protocol functions may be implemented within wireless communication devices such as UEs or BSs, and any other network entities configured for measurement and filtering operations and/or filtering coefficient signalling methods.

In some aspects, the protocol layers may be implemented within or by any of the network components of FIGS. 2A-2J, such as the gNBs (e.g., 243A/243B, 243J), and various layers of the protocol functions may be implemented by one or more central or distributed units of the gNBs (e.g., gNB-CU 229J, gNB-DU 230J).

According to some aspects, protocol layers may include one or more service access points that may provide communication between two or more protocol layers. According to some aspects, PHY 410 may transmit and receive physical layer signals 405 that may be received or transmitted respectively by one or more other communication devices (e.g., UE 201, UE 201/203, device 500). According to some aspects, physical layer signals 405 may comprise one or more physical channels.

According to some aspects, an instance of PHY 410 may process requests from and provide indications to an instance of MAC 420 via one or more physical layer service access points (PHY-SAP) 415. According to some aspects, requests and indications communicated via PHY-SAP 415 may comprise one or more transport channels. According to some aspects, an instance of MAC 420 may process requests from and provide indications to an instance of RLC 430 via one or more medium access control service access points (MAC-SAP) 425. According to some aspects, requests and indications communicated via MAC-SAP 425 may comprise one or more logical channels.

According to some aspects, an instance of RLC 430 may process requests from and provide indications to an instance of PDCP 440 via one or more radio link control service access points (RLC-SAP) 435. According to some aspects, requests and indications communicated via RLC-SAP 435 may comprise one or more RLC channels. According to some aspects, an instance of PDCP 440 may process requests from and provide indications to one or more of an instance of RRC 455 and one or more instances of SDAP 447 via one or more packet data convergence protocol service access points (PDCP-SAP) 445. According to some aspects, requests and indications communicated via PDCP-SAP 445 may comprise one or more radio bearers.

According to some aspects, an instance of SDAP 447 may process requests from and provide indications to one or more higher layer protocol entities via one or more service data adaptation protocol service access points (SDAP-SAP) 449. According to some aspects, requests and indications communicated via SDAP-SAP 449 may comprise one or more quality of service (QoS) flows. According to some aspects, RRC entity 455 may configure, via one or more management service access points (M-SAP) 450, aspects of one or more protocol layers, which may include one or more instances of PHY 410, MAC 420, RLC 430, PDCP 440, and SDAP 447. According to some aspects, an instance of RRC 455 may process requests from and provide indications to one or more NAS 457 entities via one or more RRC service access points (RRC-SAP) 456. According to some aspects, a NAS entity 457 may process requests from and provide indications to one or more higher layer protocol entities via one or more NAS service access points (NAS-SAP) 459.

The components of the illustrated device 500 may be included in a UE (e.g., UE 201, UE 203, UE 460) or a RAN node (e.g., Macro RAN node 213, LP RAN node 215, gNB 480). In some aspects, the device 500 may include fewer elements (e.g., a RAN node may not utilize application circuitry 502, and instead may include a processor/controller to process IP data received from an EPC). In some aspects, the device 500 may include additional elements such as, for example, memory/storage, display, camera, sensor, or input/output (I/O) interface. In other aspects, the components described below may be included in more than one device (e.g., said circuitries may be separately included in more than one device for Cloud-RAN (C-RAN) implementations).

The processors may be coupled with or may include memory/storage and may be configured to execute instructions stored in the memory/storage to enable various applications or operating systems to run on the device 500. In some aspects, processors of application circuitry 502 may process IP data packets received from an EPC.

For example, in some aspects, the baseband circuitry 504 may support communication with an evolved universal terrestrial radio access network (EUTRAN) or other wireless metropolitan area networks (WMAN), a wireless local area network (WLAN), a wireless personal area network (WPAN). Aspects in which the baseband circuitry 504 is configured to support radio communications of more than one wireless protocol may be referred to as multi-mode baseband circuitry.

RF circuitry 506 may enable communication with wireless networks using modulated electromagnetic radiation through a non-solid medium. In various aspects, the RF circuitry 506 may include switches, filters, amplifiers, etc. to facilitate the communication with the wireless network. RF circuitry 506 may include a receive signal path which may include circuitry to down-convert RF signals received from the FEM circuitry 508 and provide baseband signals to the baseband circuitry 504. RF circuitry 506 may also include a transmit signal path which may include circuitry to up-convert baseband signals provided by the baseband circuitry 504 and provide RF output signals to the FEM circuitry 508 for transmission.

In some aspects, the receive signal path of the RF circuitry 506 may include mixer circuitry 506A, amplifier circuitry 506B and filter circuitry 506C. In some aspects, the transmit signal path of the RF circuitry 506 may include filter circuitry 506C and mixer circuitry 506A. RF circuitry 506 may also include synthesizer circuitry 506D for synthesizing a frequency for use by the mixer circuitry 506A of the receive signal path and the transmit signal path. In some aspects, the mixer circuitry 506A of the receive signal path may be configured to down-convert RF signals received from the FEM circuitry 508 based on the synthesized frequency provided by synthesizer circuitry 506D. The amplifier circuitry 506B may be configured to amplify the down-converted signals and the filter circuitry 506C may be a low-pass filter (LPF) or band-pass filter (BPF) configured to remove unwanted signals from the down-converted signals to generate output baseband signals. Output baseband signals may be provided to the baseband circuitry 504 for further processing. In some aspects, the output baseband signals may be zero-frequency baseband signals, although this is not a requirement. In some aspects, mixer circuitry 506A of the receive signal path may comprise passive mixers, although the scope of the aspects is not limited in this respect.

In some aspects, the mixer circuitry 506A of the transmit signal path may be configured to up-convert input baseband signals based on the synthesized frequency provided by the synthesizer circuitry 506D to generate RF output signals for the FEM circuitry 508. The baseband signals may be provided by the baseband circuitry 504 and may be filtered by filter circuitry 506C. In some aspects, the mixer circuitry 506A of the receive signal path and the mixer circuitry 506A of the transmit signal path may include two or more mixers and may be arranged for quadrature down-conversion and up-conversion, respectively. In some aspects, the mixer circuitry 506A of the receive signal path and the mixer circuitry 506A of the transmit signal path may include two or more mixers and may be arranged for image rejection (e.g., Hartley image rejection).

In some aspects, the output baseband signals and the input baseband signals may be analog baseband signals, although the scope of the aspects is not limited in this respect. In some alternate aspects, the output baseband signals and the input baseband signals may be digital baseband signals. In these alternate aspects, the RF circuitry 506 may include analog-to-digital converter (ADC) and digital-to-analog converter (DAC) circuitry and the baseband circuitry 504 may include a digital baseband interface to communicate with the RF circuitry 506.

In some dual-mode aspects, a separate radio IC circuitry may be provided for processing signals for each spectrum, although the scope of the aspects is not limited in this respect. In some aspects, the synthesizer circuitry 506D may be a fractional-N synthesizer or a fractional N/N+1 synthesizer, although the scope of the aspects is not limited in this respect as other types of frequency synthesizers may be suitable. For example, synthesizer circuitry 506D may be a delta-sigma synthesizer, a frequency multiplier, or a synthesizer comprising a phase-locked loop with a frequency divider. The synthesizer circuitry 506D may be configured to synthesize an output frequency for use by the mixer circuitry 506A of the RF circuitry 506 based on a frequency input and a divider control input. In some aspects, the synthesizer circuitry 506D may be a fractional N/N+1 synthesizer.

In some aspects, frequency input may be provided by a voltage-controlled oscillator (VCO), although that is not a requirement. Divider control input may be provided by either the baseband circuitry 504 or the applications processor 502 depending on the desired output frequency. In some aspects, a divider control input (e.g., N) may be determined from a look-up table based on a channel indicated by the applications processor 502.

Synthesizer circuitry 506D of the RF circuitry 506 may include a divider, a delay-locked loop (DLL), a multiplexer and a phase accumulator. In some aspects, the divider may be a dual modulus divider (DMD) and the phase accumulator may be a digital phase accumulator (DPA). In some aspects, the DMD may be configured to divide the input signal by either N or N+1 (e.g., based on a carry out) to provide a fractional division ratio. In some example aspects, the DLL may include a set of cascaded, tunable, delay elements, a phase detector, a charge pump and a D-type flip-flop. In these aspects, the delay elements may be configured to break a VCO period up into Nd equal packets of phase, where Nd is the number of delay elements in the delay line. In this way, the DLL provides negative feedback to help ensure that the total delay through the delay line is one VCO cycle.

In some aspects, synthesizer circuitry 506D may be configured to generate a carrier frequency as the output frequency, while in other aspects, the output frequency may be a multiple of the carrier frequency (e.g., twice the carrier frequency, four times the carrier frequency) and used in conjunction with quadrature generator and divider circuitry to generate multiple signals at the carrier frequency with multiple different phases with respect to each other. In some aspects, the output frequency may be a LO frequency (f_(LO)). In some aspects, the RF circuitry 506 may include an IQ/polar converter.

FEM circuitry 508 may include a receive signal path which may include circuitry configured to operate on RF signals received from one or more antennas 510, amplify the received signals and provide the amplified versions of the received signals to the RF circuitry 506 for further processing. FEM circuitry 508 may also include a transmit signal path which may include circuitry configured to amplify signals for transmission provided by the RF circuitry 506 for transmission by one or more of the one or more antennas 510. In various aspects, the amplification through the transmit or receive signal paths may be done solely in the RF circuitry 506, solely in the FEM 508, or in both the RF circuitry 506 and the FEM 508.

In some aspects, the FEM circuitry 508 may include a TX/RX switch to switch between transmit mode and receive mode operation. The FEM circuitry may include a receive signal path and a transmit signal path. The receive signal path of the FEM circuitry may include an LNA to amplify received RF signals and provide the amplified received RF signals as an output (e.g., to the RF circuitry 506). The transmit signal path of the FEM circuitry 508 may include a power amplifier (PA) to amplify input RF signals (e.g., provided by RF circuitry 506), and one or more filters to generate RF signals for subsequent transmission (e.g., by one or more of the one or more antennas 510).

In some aspects, the PMC 512 may manage power provided to the baseband circuitry 504. In particular, the PMC 512 may control power-source selection, voltage scaling, battery charging, or DC-to-DC conversion. The PMC 512 may often be included when the device 500 is capable of being powered by a battery, for example, when the device is included in a UE. The PMC 512 may increase the power conversion efficiency while providing desirable implementation size and heat dissipation characteristics.

While FIG. 5 shows the PMC 512 coupled only with the baseband circuitry 504. However, in other aspects, the PMC 512 may be additionally or alternatively coupled with, and perform similar power management operations for, other components such as, but not limited to, application circuitry 502, RF circuitry 506, or FEM 508.

In some aspects, the PMC 512 may control, or otherwise be part of, various power saving mechanisms of the device 500. For example, if the device 500 is in an RRC Connected state, where it is still connected to the RAN node as it expects to receive traffic shortly, then it may enter a state known as Discontinuous Reception Mode (DRX) after a period of inactivity. During this state, the device 500 may power down for brief intervals of time and thus save power.

If there is no data traffic activity for an extended period of time, then the device 500 may transition off to an RRC Idle state, where it disconnects from the network and does not perform operations such as channel quality feedback, handover, etc. The device 500 goes into a very low power state and it performs paging where again it periodically wakes up to listen to the network and then powers down again. The device 500 may not receive data in this state, in order to receive data, it must transition back to RRC Connected state. An additional power saving mode may allow a device to be unavailable to the network for periods longer than a paging interval (ranging from seconds to a few hours). During this time, the device is totally unreachable to the network and may power down completely. Any data sent during this time incurs a large delay and it is assumed the delay is acceptable.

Processors of the application circuitry 502 and processors of the baseband circuitry 504 may be used to execute elements of one or more instances of a protocol stack (e.g., protocol stack described with respect to FIG. 4, FIG. 7, or FIG. 8). For example, processors of the baseband circuitry 504, alone or in combination, may be used execute Layer 3, Layer 2, or Layer 1 functionality, while processors of the application circuitry 502 may utilize data (e.g., packet data) received from these layers and further execute Layer 4 functionality (e.g., transmission communication protocol (TCP) and user datagram protocol (UDP) layers). As referred to herein, Layer 3 may comprise a RRC layer (e.g., 455, 705). As referred to herein, Layer 2 may comprise a MAC layer (e.g., 420, 702), a RLC layer (e.g., 430, 703), and a PDCP layer (e.g., 440, 704). As referred to herein, Layer 1 may comprise a PHY layer (e.g., 410, 701) of a UE/RAN node. Accordingly, in various examples, applicable means for transmitting may be embodied by such devices or media.

FIG. 6 illustrates example interfaces of baseband circuitry in accordance with some aspects. As discussed above, the baseband circuitry 504 of FIG. 5 may comprise processors 504A-504E and a memory 504G utilized by said processors. Each of the processors 504A-504E may include a memory interface, 604A-604E, respectively, to send/receive data to/from the memory 504G.

FIG. 7 is an illustration of a control plane protocol stack in accordance with some aspects. In an aspect, a control plane 700 is shown as a communications protocol stack between the UE 201/203, the RAN node 243 (or alternatively, the RAN node 245), and the AMF 247. The PHY layer 701 may in some aspects transmit or receive information used by the MAC layer 702 over one or more air interfaces. The PHY layer 701 may further perform link adaptation or adaptive modulation and coding (AMC), power control, cell search (e.g., for initial synchronization and handover purposes), and other measurements used by higher layers, such as the RRC layer 705. The PHY layer 701 may in some aspects still further perform error detection on the transport channels, forward error correction (FEC) coding/decoding of the transport channels, modulation/demodulation of physical channels, interleaving, rate matching, mapping onto physical channels, and Multiple Input Multiple Output (MIMO) antenna processing.

The MAC layer 702 may in some aspects perform mapping between logical channels and transport channels, multiplexing of MAC service data units (SDUs) from one or more logical channels onto transport blocks (TB) to be delivered to PHY via transport channels, de-multiplexing MAC SDUs to one or more logical channels from transport blocks (TB) delivered from the PHY via transport channels, multiplexing MAC SDUs onto TBs, scheduling information reporting, error correction through hybrid automatic repeat request (HARD), and logical channel prioritization.

The RLC layer 703 may in some aspects operate in a plurality of modes of operation, including: Transparent Mode (TM), Unacknowledged Mode (UM), and Acknowledged Mode (AM). The RLC layer 703 may execute transfer of upper layer protocol data units (PDUs), error correction through automatic repeat request (ARQ) for AM data transfers, and segmentation and reassembly of RLC SDUs for UM and AM data transfers. The RLC layer 703 may also maintain sequence numbers independent of the ones in PDCP for UM and AM data transfers. The RLC layer 703 may also in some aspects execute re-segmentation of RLC data PDUs for AM data transfers, detect duplicate data for AM data transfers, discard RLC SDUs for UM and AM data transfers, detect protocol errors for AM data transfers, and perform RLC re-establishment.

The PDCP layer 704 may in some aspects execute header compression and decompression of IP data, maintain PDCP Sequence Numbers (SNs), perform in-sequence delivery of upper layer PDUs at re-establishment of lower layers, perform reordering and eliminate duplicates of lower layer SDUs, execute PDCP PDU routing for the case of split bearers, execute retransmission of lower layer SDUs, cipher and decipher control plane and user plane data, perform integrity protection and integrity verification of control plane and user plane data, control timer-based discard of data, and perform security operations (e.g., ciphering, deciphering, integrity protection, integrity verification, etc.).

In some aspects, primary services and functions of the RRC layer 705 may include broadcast of system information (e.g., included in Master Information Blocks (MIBs) or System Information Blocks (SIBs) related to the non-access stratum (NAS)); broadcast of system information related to the access stratum (AS); paging initiated by 5GC 220 or NG-RAN 239/236, establishment, maintenance, and release of an RRC connection between the UE and NG-RAN (e.g., RRC connection paging, RRC connection establishment, RRC connection addition, RRC connection modification, and RRC connection release, also for carrier aggregation (CA) and Dual Connectivity (DC) in NR or between E-UTRA and NR); establishment, configuration, maintenance, and release of Signalling Radio Bearers (SRBs) and Data Radio Bearers (DRBs); security functions including key management, mobility functions including handover and context transfer, UE cell selection and reselection and control of cell selection and reselection, and inter-radio access technology (RAT) mobility; and measurement configuration for UE measurement reporting. The MIBs and SIBs may comprise one or more information elements (IEs), which may each comprise individual data fields or data structures. The RRC layer 705 may also, in some aspects, execute QoS management functions, detection of and recovery from radio link failure, and NAS message transfer between the NAS 706 in the UE and the NAS 706 in the AMF 232.

In some aspects, the following NAS messages can be communicated during the corresponding NAS procedure, as illustrated in Table 1 below:

TABLE 1 5G NAS 5G NAS 4G NAS 4G NAS Message Procedure Message name Procedure Registration Initial Attach Request Attach Request registration procedure procedure Registration Mobility Tracking Area Tracking area Request registration Update (TAU) updating update Request procedure procedure Registration Periodic TAU Request Periodic Request registration tracking area update updating procedure procedure Deregistration Deregistration Detach Detach Request procedure Request procedure Service Service request Service Service request Request procedure Request or procedure Extended Service Request PDU Session PDU session PDN PDN Establishment establishment Connectivity connectivity Request procedure Request procedure

In some aspects, when the same message is used for more than one procedure, then a parameter can be used (e.g., registration type or TAU type) which indicates the specific purpose of the procedure, e.g. registration type=“initial registration”, “mobility registration update” or “periodic registration update”.

The UE 201 and the RAN node 243/245 may utilize an NG radio interface (e.g., an LTE-Uu interface or an NR radio interface) to exchange control plane data via a protocol stack comprising the PHY layer 701, the MAC layer 702, the RLC layer 703, the PDCP layer 704, and the RRC layer 705.

The non-access stratum (NAS) protocols 706 form the highest stratum of the control plane between the UE 201 and the AMF 247 as illustrated in FIG. 7 In aspects, the NAS protocols 706 support the mobility of the UE 201 and the session management procedures to establish and maintain IP connectivity between the UE 201 and the UPF 249. In some aspects, the UE protocol stack can include one or more upper layers, above the NAS layer 706. For example, the upper layers can include an operating system layer 724, a connection manager 720, and application layer 722. In some aspects, the application layer 722 can include one or more clients which can be used to perform various application functionalities, including providing an interface for and communicating with one or more outside networks. In some aspects, the application layer 722 can include an IP multimedia subsystem (IMS) client 726.

The NG Application Protocol (NG-AP) layer 715 may support the functions of the N2 and N3 interface and comprise Elementary Procedures (EPs). An EP is a unit of interaction between the RAN node 243/245 and the 5GC 220. In certain aspects, the NG-AP layer 715 services may comprise two groups: UE-associated services and non-UE-associated services. These services perform functions including, but not limited to: UE context management, PDU session management and management of corresponding NG-RAN resources (e.g. Data Radio Bearers (DRBs)), UE capability indication, mobility, NAS signalling transport, and configuration transfer (e.g. for the transfer of Self-Organizing Network (SON) information).

The Stream Control Transmission Protocol (SCTP) layer (which may alternatively be referred to as the SCTP/IP layer) 714 may ensure reliable delivery of signalling messages between the RAN node 243/245 and the AMF 247 based, in part, on the IP protocol, supported by the IP layer 713. The L2 layer 712 and the L1 layer 711 may refer to communication links (e.g., wired or wireless) used by the RAN node 243/245 and the AMF 247 to exchange information. The RAN node 243/245 and the AMF 247 may utilize an N2 interface to exchange control plane data via a protocol stack comprising the L1 layer 711, the L2 layer 712, the IP layer 713, the SCTP layer 714, and the S1-AP layer 715.

FIG. 8 is an illustration of a user plane protocol stack in accordance with some aspects. In this aspect, a user plane 800 is shown as a communications protocol stack between the UE 201/203, the RAN node 243 (or alternatively, the RAN node 245), and the UPF 249. The user plane 800 may utilize at least some of the same protocol layers as the control plane 700. For example, the UE 201/203 and the RAN node 243 may utilize an NR radio interface to exchange user plane data via a protocol stack comprising the PHY layer 701, the MAC layer 702, the RLC layer 703, the PDCP layer 704, and the Service Data Adaptation Protocol (SDAP) layer 716. The SDAP layer 716 may, in some aspects, execute a mapping between a Quality of Service (QoS) flow and a data radio bearer (DRB) and a marking of both DL and UL packets with a QoS flow ID (QFI). In some aspects, an IP protocol stack 813 can be located above the SDAP 716. A user datagram protocol (UDP)/transmission control protocol (TCP) stack 820 can be located above the IP stack 813. A session initiation protocol (SIP) stack 822 can be located above the UDP/TCP stack 820, and can be used by the UE 201/203 and the UPF 249.

The General Packet Radio Service (GPRS) Tunneling Protocol for the user plane (GTP-U) layer 804 may be used for carrying user data within the 5G core network 220 and between the RAN (e.g., 210-J) and the 5G core network 220. The user data transported can be packets in IPv4, IPv6, or PPP formats, for example. The UDP and IP security (UDP/IP) layer 803 may provide checksums for data integrity, port numbers for addressing different functions at the source and destination, and encryption and authentication on the selected data flows. The RAN node 243/245 and the UPF 249 may utilize an N3 interface to exchange user plane data via a protocol stack comprising the L1 layer 911, the L2 layer 912, the UDP/IP layer 803, and the GTP-U layer 804. As discussed above with respect to FIG. 6, NAS protocols support the mobility of the UE 201 and the session management procedures to establish and maintain IP connectivity between the UE 201 and the UPF 249.

Specifically, FIG. 9 shows a diagrammatic representation of hardware resources 900 including one or more processors (or processor cores) 910, one or more memory/storage devices 920, and one or more communication resources 930, each of which may be communicatively coupled via a bus 940. For aspects in which node virtualization (e.g., NFV) is utilized, a hypervisor 902 may be executed to provide an execution environment for one or more network slices or sub-slices to utilize the hardware resources 900

The processors 910 (e.g., a central processing unit (CPU), a reduced instruction set computing (RISC) processor, a complex instruction set computing (CISC) processor, a graphics processing unit (GPU), a digital signal processor (DSP) such as a baseband processor, an application specific integrated circuit (ASIC), a radio-frequency integrated circuit (RFIC), another processor, or any suitable combination thereof) may include, for example, a processor 912 and a processor 914.

The memory/storage devices 920 may include main memory, disk storage, or any suitable combination thereof. The memory/storage devices 920 may include, but are not limited to, any type of volatile or non-volatile memory such as dynamic random-access memory (DRAM), static random-access memory (SRAM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), Flash memory, solid-state storage, etc.

The communication resources 930 may include interconnection or network interface components or other suitable devices to communicate with one or more peripheral devices 904 or one or more databases 906 via a network 908. For example, the communication resources 930 may include wired communication components (e.g., for coupling via a Universal Serial Bus (USB)), cellular communication components, NFC components, Bluetooth® components (e.g., Bluetooth® Low Energy), Wi-Fi® components, and other communication components.

Instructions 950 may comprise software, a program, an application, an applet, an app, or other executable code for causing at least any of the processors 910 to perform any one or more of the methodologies discussed herein. The instructions 950 may reside, completely or partially, within at least one of the processors 910 (e.g., within the processor's cache memory), the memory/storage devices 920, or any suitable combination thereof. Furthermore, any portion of the instructions 950 may be transferred to the hardware resources 900 from any combination of the peripheral devices 904 or the databases 906. Accordingly, the memory of processors 910, the memory/storage devices 920, the peripheral devices 904, and the databases 906 are examples of computer-readable and machine-readable media. Accordingly, in various examples, applicable means for storing may be embodied by such devices or media.

FIG. 10 illustrates a block diagram of an example machine 1000 upon which any one or more of the techniques (e.g., methodologies) discussed herein may be performed, for example, measurement and filtering and/or filtering coefficient configuration operations. Examples, as described herein, may include, or may operate by, logic or a number of components, or mechanisms in the machine 1000. Circuitry (e.g., processing circuitry) is a collection of circuits implemented in tangible entities of the machine 1000 that include hardware (e.g., simple circuits, gates, logic, etc.). Circuitry membership may be flexible over time. Circuitries include members that may, alone or in combination, perform specified operations when operating. In an example, hardware of the circuitry may be immutably designed to carry out a specific operation (e.g., hardwired). In an example, the hardware of the circuitry may include variably connected physical components (e.g., execution units, transistors, simple circuits, etc.) including a machine readable medium physically modified (e.g., magnetically, electrically, moveable placement of invariant massed particles, etc.) to encode instructions of the specific operation. In connecting the physical components, the underlying electrical properties of a hardware constituent are changed, for example, from an insulator to a conductor or vice versa. The instructions enable embedded hardware (e.g., the execution units or a loading mechanism) to create members of the circuitry in hardware via the variable connections to carry out portions of the specific operation when in operation. Accordingly, in an example, the machine readable medium elements are part of the circuitry or are communicatively coupled to the other components of the circuitry when the device is operating. In an example, any of the physical components may be used in more than one member of more than one circuitry. For example, under operation, execution units may be used in a first circuit of a first circuitry at one point in time and reused by a second circuit in the first circuitry, or by a third circuit in a second circuitry at a different time. Additional examples of these components with respect to the machine 1000 follow. Accordingly, in various examples, applicable means for processing (e.g., receiving, decoding, updating, configuring, transmitting, modifying, etc.) may be embodied by such processing circuitry.

In alternative aspects, the machine 1000 may operate as a standalone device or may be connected (e.g., networked) to other machines. In a networked deployment, the machine 1000 may operate in the capacity of a server machine, a client machine, or both in server-client network environments. In an example, the machine 1000 may act as a peer machine in peer-to-peer (P2P) (or other distributed) network environment. The machine 1000 may be a personal computer (PC), a tablet PC, a set-top box (STB), a personal digital assistant (PDA), a mobile telephone, a web appliance, a network router, switch or bridge, or any machine capable of executing instructions (sequential or otherwise) that specify actions to be taken by that machine. Further, while only a single machine is illustrated, the term “machine” shall also be taken to include any collection of machines that individually or jointly execute a set (or multiple sets) of instructions to perform any one or more of the methodologies discussed herein, such as cloud computing, software as a service (SaaS), other computer cluster configurations.

The machine (e.g., computer system) 1000 may include a hardware processor 1002 (e.g., a central processing unit (CPU), a graphics processing unit (GPU), a hardware processor core, or any combination thereof), a main memory 1004, a static memory (e.g., memory or storage for firmware, microcode, a basic-input-output (BIOS), unified extensible firmware interface (UEFI), etc.) 1006, and mass storage 1008 (e.g., hard drive, tape drive, flash storage, or other block devices) some or all of which may communicate with each other via an interlink (e.g., bus) 1030. The machine 1000 may further include a display unit 1010, an alphanumeric input device 1012 (e.g., a keyboard), and a user interface (UI) navigation device 1014 (e.g., a mouse). In an example, the display unit 1010, input device 1012 and UI navigation device 1014 may be a touch screen display. The machine 1000 may additionally include a storage device (e.g., drive unit) 1008, a signal generation device 1018 (e.g., a speaker), a network interface device 1020, and one or more sensors 1016, such as a global positioning system (GPS) sensor, compass, accelerometer, or other sensor. The machine 1000 may include an output controller 1028, such as a serial (e.g., universal serial bus (USB), parallel, or other wired or wireless (e.g., infrared (IR), near field communication (NFC), etc.) connection to communicate or control one or more peripheral devices (e.g., a printer, card reader, etc.).

Registers of the processor 1002, the main memory 1004, the static memory 1006, or the mass storage 1008 may be, or include, a machine readable medium 1022 on which is stored one or more sets of data structures or instructions 1024 (e.g., software) embodying or utilized by any one or more of the techniques or functions described herein. The instructions 1024 may also reside, completely or at least partially, within any of registers of the processor 1002, the main memory 1004, the static memory 1006, or the mass storage 1008 during execution thereof by the machine 1000. In an example, one or any combination of the hardware processor 1002, the main memory 1004, the static memory 1006, or the mass storage 1008 may constitute the machine readable media 1022. While the machine readable medium 1022 is illustrated as a single medium, the term “machine readable medium” may include a single medium or multiple media (e.g., a centralized or distributed database, or associated caches and servers) configured to store the one or more instructions 1024.

The term “machine readable medium” may include any medium that is capable of storing, encoding, or carrying instructions for execution by the machine 1000 and that cause the machine 1000 to perform any one or more of the techniques of the present disclosure, or that is capable of storing, encoding or carrying data structures used by or associated with such instructions. Non-limiting machine readable medium examples may include solid-state memories, optical media, magnetic media, and signals (e.g., radio frequency signals, other photon-based signals, sound signals, etc.). In an example, a non-transitory machine-readable medium comprises a machine readable medium with a plurality of particles having invariant (e.g., rest) mass, and thus are compositions of matter. Accordingly, non-transitory machine-readable media are machine readable media that do not include transitory propagating signals. Specific examples of non-transitory machine readable media may include: non-volatile memory, such as semiconductor memory devices (e.g., Electrically Programmable Read-Only Memory (EPROM), Electrically Erasable Programmable Read-Only Memory (EEPROM)) and flash memory devices; magnetic disks, such as internal hard disks and removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks.

The instructions 1024 may be further transmitted or received over a communications network 1026 using a transmission medium via the network interface device 1020 utilizing any one of a number of transfer protocols (e.g., frame relay, internet protocol (IP), transmission control protocol (TCP), user datagram protocol (UDP), hypertext transfer protocol (HTTP), etc.). Example communication networks may include a local area network (LAN), a wide area network (WAN), a packet data network (e.g., the Internet), mobile telephone networks (e.g., cellular networks), Plain Old Telephone (POTS) networks, and wireless data networks (e.g., Institute of Electrical and Electronics Engineers (IEEE) 802.11 family of standards known as Wi-Fi®), IEEE 802.15.4 family of standards, peer-to-peer (P2P) networks, among others. In an example, the network interface device 1020 may include one or more physical jacks (e.g., Ethernet, coaxial, or phone jacks) or one or more antennas to connect to the communications network 1026. In an example, the network interface device 1020 may include a plurality of antennas to wirelessly communicate using at least one of single-input multiple-output (SIMO), multiple-input multiple-output (MIMO), or multiple-input single-output (MISO) techniques. The term “transmission medium” shall be taken to include any intangible medium that is capable of storing, encoding or carrying instructions for execution by the machine 1000, and includes digital or analog communications signals or other intangible medium to facilitate communication of such software. A transmission medium is a machine readable medium.

It is important to note that aspects of the method 1100 may include additional or even fewer operations or processes in comparison to what is illustrated in FIG. 11. In addition, aspects of the method 1100 are not necessarily limited to the chronological order that is shown in FIG. 11. In describing the method 1100, reference may be made to FIGS. 1-12, although it is understood that the method 1100 may be practiced with any other suitable systems, interfaces and components. For example, reference may be made to systems 200A-200J described earlier for illustrative purposes, but the techniques and operations of the method 1100 are not so limited. In some aspects, operations of the method 1100 can be performed by a device (or an apparatus of the device) such as a wireless communication device, UE, or any other network device as described herein. Further, operations can be performed by virtualized functions of the SDN or NFV networks described herein.

In operation 1104, the UE can filter (e.g., adapt a layer 3 filter to performing filtering of) the at least one of the cell measurement result and the beam measurement result, according to the measurement configuration IE. In some aspects, if the measurement quantity parameter indicates the cell measurement quantity, the UE (e.g., UE processing circuitry) can adapt the layer 3 filter to perform filtering of the cell measurement result according to the RS type filter configuration and the filter coefficient to determine a measurement evaluation input for a measurement reporting operation. In some aspects, if the measurement quantity parameter indicates the beam measurement quantity, the UE can adapt the layer 3 filter to perform filtering of the beam measurement result according to the RS type filter configuration and the filter coefficient to determine a beam measurement selection input for a beam measurement selection operation.

In operation 1106, the UE can encode a measurement report for transmission to a BS (e.g., gNB, eNB). The measurement report can include at least one of measurement report information and beam measurement selection information based on the measurement reporting operation and the beam measurement selection operation. The UE memory can be configured to store the measurement configuration IE. In some aspects, the measurement quantity parameter can include at least one of a cell quantity coefficient or a beam quantity coefficient and the cell quantity coefficient can be a separate coefficient from the beam quantity coefficient.

The RS-type filter configuration can include at least one of a SSB-based coefficient or a CSI-RS-based coefficient and the SSB-based coefficient can be a separate coefficient from the CSI-RS-based coefficient. The filter coefficient can be configured as a RSRP filter coefficient, an RSRQ filter coefficient or a RS-SINR filter coefficient, and the RSRP filter coefficient, the RSRQ filter coefficient, and the RS-SINR filter coefficient can be separate (e.g., layer 3) filtering coefficients.

FIG. 12 illustrates generally a flow of an exemplary method 1200 of configuring filtering coefficients, in accordance with some aspects. In some aspects, operations of the method 1200 can be performed by a device (or an apparatus of the device) such as a network entity, BS (e.g., gNB, eNB), or any other network device as described herein. Further, operations can be performed by virtualized functions of the SDN or NFV networks described herein.

In operation 1202, a BS can configure one or more filtering coefficients and/or configurations. For example, the BS can configure an RS-type filter configuration to include at least one of a SSB-based coefficient or a CSI-RS-based coefficient and the SSB-based coefficient can be a separate coefficient from the CSI-RS-based coefficient. The BS can also configure at least one of a RSRP filter coefficient, a RSRQ filter coefficient and a RS-SINR filter coefficient and the RSRP filter coefficient, the RSRQ filter coefficient and the RS-SINR filter coefficient can be separate layer 3 filtering coefficients. The BS can configure a measurement quantity parameter to include at least one of a cell quantity coefficient or a beam quantity coefficient and the cell quantity coefficient can be a separate coefficient from the beam quantity coefficient. The BS can also configure a measurement configuration IE to include the RS-type filter configuration, the measurement quantity parameter and at least one of the layer 3 filtering coefficients.

In operation 1204, the BS can encode RRC signalling to include the measurement configuration IE, for transmission to a UE, for determining at least one of a measurement evaluation input for a measurement reporting operation or a beam measurement selection input for a beam measurement selection operation. In operation 1206, the BS can decode, from signalling received from the UE, a measurement report including at least one of measurement report information and beam measurement selection information, based on the measurement configuration IE. In some aspects, the memory of the BS can be configured to store the measurement report received from the UE.
